T0 at whom it may concern.-

Be it known that 1, JOHN STREETER WRIGHT, Jr., residing at Ghurchland,in the county of Norfolk and State of Virginia, have invented a new andImproved Ventilated Barrel, of which the following is a specification.

Barrels of this class have been form ed of an inner and outer set ofstaves having straight parallel edges, the same having been arranged inpairs, so that one stave lay upon another and the sides of bothcoincided throughout. Such barrels lacked requisite strength andrigidity, owing, chiefly, to the fact that the inner or outer staves didnot overlap the adjacent ones at their ends, and the openings betweenthe pairs of staves also extended to the ends of the staves inconsequence of the bulge or convexity of the barrels. Such barrels soonbecome weakened and distorted. Barrels have also been constructed of aninner and outer set of staves which were Wedgeshaped, each one in theouter set being placed uponan inner one and their respective broad andnarrow ends reversed. In constructing such barrels a loss is incurred incutting up sheets of veneers to form the staves-that is to say, a stripis wasted at each end of a veneer sheet-the loss amounting to half astave for every fifteen staves cut. Further, owing to the care,attention, and difficulty of placing and alternating the wedgeshapedstaves inside and outside the time required to assemble them isconsiderably greater than in the case of staves having parallel sides,and, finally, the openings between the adjacent pairs of staves extendbut a short distance beyond the lengthwise middle.

- In constructing my barrel I combine features of both above types andattain advantages possessed by neither.

The details of construction and combination of parts are as follows:

In accompanying drawings, Figure 1 isa perspective View of my improvedbarrel. Fig. 2 is a central horizontal section on line 2 2, Fig. 1. Fig.3 is a cross-section on line 3 3, Fig. 1. Fig. 4: is a face view of twostaves placed together.

The body of the barrel is composed of two sets of veneer staves, one setbeing arranged within the other. The outer staves 1 have at their ends,which remain in contact, as

shown. The diameter of the barrel. being about seventeen inches at theends, it is impracticable to make the said staves more than three inchesWide or thereabout, since they must be bent or curved transverselycorresponding to the diameter of the barrel. These ends are in lateralcontact.

The inner staves 3 have straight sides, but are wedge-shaped. They aremade of such proportions that at the middle of their length they havethe same width as the outer staves l. WVhen arranged in the barrel,these staves 3 are alternately reversed, so that the narrow end of oneis adjacent to the wide ends of the two adjacent ones and in contacttherewith. The outer parallel-sided staves 1 and inner Wedge-shapedstaves 3 are placed flat together in pairs, so that their middleportions, which are of equal width, as before described, coincide, asshown in Figs. 1 and 4. The inner staves 3 are bent so as to have thesame bilge as the outer ones 1, and therefore separated from each otherby an elliptical opening 2 in the same manner. This opening extendsnearly half the length of the barrel. By this combination andarrangement of parallelsided and wedge-shaped staves the openings 2 forventilation are longer and larger than would be practicable ifWedge-shaped staves alone were used both inside and out and the barrelis stronger and stiffer than if parallelsided staves were used on theinside.

A still more important advantage is attained in respect to economy ofconstruction, since it requires considerably less time to assemble thestaves 1 3 than to assemble two sets of wedge-shaped ones--that is tosay, no care is necessary and no delay encountered in selecting andplacing the outer staves l in position on the inner ones, since itmatters not which end of the outer ones is placed up or down. A furthereconomy is attained by reason of the saving of material in cutting upveneer sheets, as before stated. The saving in time and labor thuseffected enables my barrel to be sold at a lower price than others ofits special class.

Four hoops at are employed, one at each Having thus described myinvent-ion, what I claim, and desire to secure by Letters Patent, is

The improved ventilated barrel composed of an outer set of straight,parallel-sided staves whose ends are in contact, and an innerset ofwedge-shaped staves, arranged with their narrow and wider endsalternating, the 1 I end and two interinediately. I
